Which of the following best describes the primary duty of a broker?

The primary duty of a broker is best described as facilitating communication between buyers and sellers. In the real estate context, this role involves acting as an intermediary who helps negotiate and promote transactions between parties with differing interests. By fostering open communication, brokers can better understand their clients' needs and preferences, thereby guiding both buyers and sellers through the process effectively.

Additionally, this role encompasses providing valuable market insights, advising clients on pricing, and coordinating property viewings. While brokers may engage in other activities, such as assisting with marketing properties or managing rental properties, these functions are secondary to their essential responsibility of ensuring smooth and effective communication throughout the transaction process.
